How Linux automatically generates arrays from 1 to 100 in the shell

Before writing a shell script, you need to automatically create 1-100 of the text without knowing how to create it. Baidu finally know the way to create.

There are a lot of ways to create 1-100 in a shell script, so I'll say two easy-to-understand and convenient ways here:

The first method:

For i in {1..100}

Do

Echo $i

Done

Using {1..100} is simple and straightforward, and you can also see the effect directly in Linux command mode: echo {1..100}.

The second method:

Using the SEQ function

For i in ' SEQ 1 100 '

Do

Echo $i

Done

Using the SEQ implementation is also a particularly handy way to do this in Linux: Seq 1 100. Look at the effect on your own.
